SUBSEQUENT EVENTS The Company entered into a Collaborative Agreement with BioLite, Inc., a company incorporated under the laws of Taiwan, and a subsidiary of the Company, (“BioLite”) on December 29, 2015, and then entered into two addendums to such agreement (as amended and revised, (the “Agreement”)). Pursuant to the Agreement, the Company acquired the sole licensing rights to develop and commercialize for therapeutic purposes six compounds from BioLite. In accordance with the terms of the Agreement, the Company shall pay BioLite (i) milestone payments of up to $100 million in cash and equity of the Company or equity securities owned by it at various stages on a schedule dictated by BioLite’s achievements of certain milestones, as set forth in the Agreement (the “Milestone Payments”) and (ii) a royalty payment equal to 5% of net sales of the drug products when ABV-1501 is approved for sale in the licensed territories. If BioLite fails to reach any of the milestones in a timely manner, it may not receive the rest of the payments from the Company. According to the Agreement, after Phase II clinical trials are completed, 15% of the Milestone Payment becomes due and shall be paid in two stages: (i) 5% no later than December 31, 2021 (the “December 2021 Payment”) and (ii) 10% no later than December 31, 2022. On February 12, 2022, the Company’s Board of Directors determined that the December 2021 Payment, which is equal to $5,000,000, shall be paid via the cancellation of certain outstanding debt, in the amount of $5,000,000, that BioLite owes the Company as of December 31, 2021. On February 22, 2022, the parties entered into an amendment to the Agreement allowing the Company to make all payments due under the Agreement via the forgiveness of debt, in equal value, owed by BioLite to the Company. This was a related party transaction and was conducted at arm’s length. In addition to the Company’s board of directors approving the modification of terms of the Agreement, the Company’s audit committee approved them too. The Board believes it is in the Company’s best interest to cancel outstanding debt and apply it to the December 2021 Payment. Following such approval, the Company and BioLite entered into an amendment to the Agreement reflecting the modified payment method. The Company also issued an aggregate of 1,306,007 shares of common stock to consultants, who provided consulting services in January 2022; it issued an additional 75,000 shares to another consultant in March 2022, based on the 6-month consulting and advisory services agreement, with a monthly payment of USD $15,000. The Company has evaluated subsequent events through the date which the financial statements were available to be issued. All subsequent events requiring recognition as of December 31, 2021 have been incorporated into these financial statements and there are no other subsequent events that require disclosure in accordance with FASB ASC Topic 855, “Subsequent Events.”
